Answer:

10x^2-x+3 miles.

Step-by-step explanation:

It is given that,

Total length of park trail = 10x^2+4x+2 miles

Total length traveled by hiker = 5x-1 miles

We need to find the length of trail hiker need to travel to get to the end of the trail.

Required length =10x^2+4x+2-(5x-1)

               =10x^2+4x+2-5x+1

               =10x^2+(4x-5x)+(2+1)

               =10x^2-x+3

Therefore, hiker need to travel 10x^2-x+3 miles to get to the end of the trail.

Rational expression. simplify<br> 36m-48m over 6m.
ladessa [460]
One way is to find common factors

example

8/6=4/3 because 8/6, 8 and 6 have common factor of 2 so divide that out to get 4/3
basically divide the LCM from each

so factor

we can combine 36m-48m into -12m
we have
-12m/6m

common factor is 6m
-12m/6m=(-2)/1 times (6m)/(6m)=-2 times 1=-2

answer is -2

Plastic parts produced by an injection-molding operation are checked for conformance to specifications. Each tool contains 15 ca
Rainbow [258]

Answer:

(A) 0.006593 or 0.6593%

(B) 0.01538 or 1.538%

Step-by-step explanation:

The total number of possibilities to pick 3 parts out of 15 possible parts is given by the following combination:

n=\frac{15!}{(15-3)!3!}=\frac{15*14*13}{3*2*1}\\n=455\ ways\\

(A) There are only three possibilities for which the inspector finds exactly one nonconforming part (NCC, CNC, CCN). Therefore, the probability is:

P(N=1) = \frac{3}{455}=0.006593 =0.6593\%

(B) There are three possibilities  for which the inspector finds exactly one nonconforming part, three possibilities for two nonconforming parts (NNC, CNN, NCN), and one possibility for all nonconforming parts (NNN). The probability that the inspector finds at least one nonconforming part is:

P(N>0) =P(N=1)+P(N=2)+P(N=3) \\P(N>0) = \frac{3}{455}+ \frac{3}{455}+ \frac{1}{455}\\P(N>0) =0.01538 =1.538\%
